Specification of Letters Patent.

Patented March 6, 1906.

To all. whom it may concern:

Be it known that I, GEORG B. LAMB, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Presses, of which the following is a specification, reference being had therein to the accompanying drawings. 7

My invention relates to new and useful improvements in presses, and refers more particularly to that type of press which is commonly known in the art as a cut-and-carry press.

It is the object of my invention, among other thin s, to construct a press of this character in w ich the double-acting mechanism will be actuated from a shaft out of the axial line of movement of said plunger, to rovide and mount the several single-actin p un ers whereby they may be accurately a juste independently of eachother and each of said plungers removable without interfering with the adjustment of any of the other plungers, to provide knock-out mechanism that can be positively actuated and so mounted as to be readily removed without disarranging the tools and each of the knock-out rods removed separately, if desired, to provide asimple and effective means for carrying the metal successively from one tool to another during the several operations, and in eneral to so design and construct the severe parts of my new and improved press that it may he ecoglomically constructed and readily assem- Referrin to the drawings, in which like numerals 0 reference designate like parts in the several figures, Figure 1 is a front elevation of my new and improved press. Fig. 2 is a side elevation looking from the left of Fig. 1. Fig. 3 is a vertical section thereof upon line A B of Fig. 1. Fig. 4 is a detail p an view of a portion of theknock-out mechanism. Fi 5 is a side elevation of a portion of the doub e-acting mechanism. Fig. 6 is a plan view of a portion of the crank-shaft, the double-acting gate and its operative mechanism, and some of the-pitmen for the singleacting plungers. Fi 7 is a fragmentary plan view 0 the sing e-acting lungers and adjacent parts, taken upon line l D of Fig. 3. Fig. 8 is a front elevation of the caps for the single-acting plunger. Fig. 9 is a plan view of the carrying mechanism. Fig. 10 is a front elevation thereof with some of the parts in section. Fi l1 is an end view thereof looking from he right of Figs. "Qend 10. Fig. 12 is an elevation of the cams and bellcrank for giving the carr ing mechanism an in-and-out movement. Fig. 13 is a sectional view of some portions of the carrying mechanism, taken upon line E of Fig. 2. Fig. 14 is a fragmentary plan view of the rocksleeve. Fig. 15 is a plan view of the feed-roll mechanism with a portion of the arts shown in section. Fi 16 is a side e evation thereof, a portion 0 the gears being broken awa Fig. 17 is a sectional elevation of the double-acting plunger. Fig. 18 is a sectional plan view thereof, taken upon line G H of Fig. 17. Fig. 19 is a sectional lan view thereof, taken upon line 5 K of Fig. 17. Fig. 20 is an enlarged plan view of the carrier-finger mechanism, and Fig. 21 is an elevation thereof.

Referring to the drawings, the numeral 1 designates the frame of the machine, which is supported upon legs or standards 2; 3, the back shaft, which is journaled in the frame and the bracket 8 affixed thereto and upon which is fixed a pulley 4 and pinion 5, which meshes into and drives a gear 6 upon the crank-shaft 7, that is journaled in the frame. A clutch mechanism actuated from a treadle is usually provided to start and stop. the mechanism as desired. As any of the many he used upon my improved press,I have not illustrated this mechanism in the drawings.

In the press illustrated there are five singleacting plungers 9 which are octagonal in cross-section and are vertically movable in guideways in the front of the part'lO, integral with the frame and held therein b the caps 11. It will be seen from the sectional view in Fig. 7 that the plungers have no frictional engagement upon two of its sides, one of said sides being within the guideway in part 10 and the other within the cap 11, this being designed so that all wear upon the parts may be taken up and the plungers have the proper frictional enga ement at all times. The caps 11 are provide with lips 12 to prevent their one side thereof and a wing 14 upon the other side, the wing and recess being of the same lateral displacement and with a recess 13 in forms of clutch and treadle mechanism may length, so that when the caps are fastened to the part 10 the wing upon one cap will enter and be held within the recess in the cap next adjoining. The 'cap is thus held against lateral movement and securely fastened upon both sides of the plunger in such manner as to permit the same to be readily detached with out disturbing the cap upon either side thereof. The necessary tools for performing the several operations may be fastened in or to the lower end of the plungers, as desired, and in Fig. 3 I have illustrated such tool as a drawing-punch, (designated 24,) which is held within a punch-holder 25, fixed to the bottom side of the plunger. The plungers 9 are actuated by means of the pitmen 15, which are connected at one end with the cranks 16 upon the shaft 7 and to the toggles 17 at the other end. The lower toggle is connected by the pin 18 with the plungers 9 and the upper toggle by the pin 19 to the backing-block 20, which is adjustable vertically by the screw 21, threaded throu h the frame 1 and impinging against said backing-block 20, and the screw 22, which passes through the screw 21 and is threaded into said backing-block. These several backing-blocks are secured in their adjusted positions b 7 the bolts 23 in such manner as to permit the to gle mechanism of each of the single-acting pTungers to be removed without disturbing any of the other toggle mechanisms.

The double-acting mechanism comprises a lower gate 26 and an upper gate 27, each of which 1s rovided with grooves 28, into which are fitted the ways 29, that are bolted to the frame 1. Integral with the lower gate is an upwardly-projectin body ortion 30, which is exteriorly threa ed an passes through the gate 27 havin the check-nuts 31 and 32 thereon and by W ch meansthe position of the two gates in relation to each other are adjusted and rigidly locked together. These gates are actuate vertically liqy means of the cams 33 and 34, which are Xed upon the crank-shaft 7; the rock-arm 35, mounted upon the shaft 36, that is fixed within the frame 1; links 37, pivotally secured at their lower ends to the gate 27 and at their upper ends to the arm 38 upon the rock-arm 35, lateral displacement of the links being prevented by the caps 39, which are bolted to the upper gate 27, and cam rolls 40 and 41, which lie against the faces of the cams 33 and 34, respectively. Rotation of the shaft 7 and the cam 34 imparts a rocking movement to the rock-arm 35 and moves the gates 27 and 26 downwardly, and the engagement of the roll 41 with the cam 34 returns the gates to their original positions, the earns 33 and 34 being so shaped and timed as to rovide for this movement. To the under side of the gate 26 is preferably secured the cutting-punch 42, which engages with a die fixed to the frame and pierces the blank from the metal strip.

Vertically movable within the lower gate 26 is the drawin -plunger 43, which is actuated in substantiafly the same manner as the single-acting plungers 9, there being a pitman 44, which is actuated from a crank upon the shaft 7, and toggles 45, the lower of said toggles being connected with the plunger 43 and the upper toggle with the backing'block 46, which is adjusted and secured in the manner described for the backin -blocks 20. Fixed in the lower end of this p unger 43 is a drawing-punch 47, which is held therein by an of the means common to the art. Heretofbre it has been the practice to operate the doubleacting mechanism of a press from a shaft directly above the axial line of movement of the parts; but this construction is objectionable and is overcome in my invention by positively operating the cutting and drawing parts from a shaft that is in the rear of their axial line of movement.

The feed mechanism comprises the rolls 48, journaled in the roll-frame 49, which is fixed to the frame 1, each of said rolls having a gear fixed thereto and which mesh into each other, with the gear upon the u per roll meshing into a gear 51, which is fixe upon a shaft 52, journaled in the side of the frame 1 a pawl-plate 53, loosely mounted u on the shaft 52 and carrying a pawl 54, w ich engages the teeth upon the ratchet 55, fixed to the shaft 52, a cam 56, fixed upon the shaft 7; a yoke 57, that is pivotally secured to the frame 1 u on the stud 58 and carrying the rolls 59, w iich en age the face of the cam 56 a block 60, slidab e upon the yoke 57 and secured in any of its adjusted positions by a bolt 61, and a rod 62, connecting the block 60 with the pawl-plate 53. The rotation of the 'cam 56 oscillates the yoke 57 and through the rods 62 the pawl 54 is actuated, and engagement of this pawl with the ratchet-disk im 'arts a rotary movement to the shaft 52, w 'ch is communicated to the rolls 48 through the gears 51 and 50. The length of the feed can be varied by shifting the position of the block upon the yoke 57 it being apparent that the closer the block is to the stud 58 the less the movement of the pawlplate 53. The end of the shaft 52 is squared, as shown in Fig. 15, so as to permit of the manual rotation of the shaft 52 and rolls 48. Fixed within the roll-frame 49 is the guideshaft 63, having thereon the adjustable stops 64, between which the metal strip is fed before passing between the rolls, the adjustment of these sto s 64 determining the lateral position of t e strip as presented beneath the cutting and drawing punches.

Beneath the frame 1 is the shaft 65, which is rotatabl driven from the crank-shaft 7 by the helica ear 66 thereon, which meshes into the hefical gear 67 upon the vertical shaft 68, that is rotatably mounted in the boxes 69, and the beveled gear 70, which meshes into and drives the beveled gear 71 upon the shaft 65. In Fig. 2 the helical gear 66 is not shown, but removed, so as to more clearly show the construction and operation of the feed-cam and yoke. 1

Bolted to the under side of the frame 1 is the bracket 72, having the laterally-projecting horizontally-slotted lugs 73 integral therewith. Upon either side of these arms are the knockout-levers 74, which are con nected at their rear ends by a stud 75 of sub stantially the same diameter as the width of the slot in the arm 72 and having nuts upon either end thereof, as shown in Fig. 4. The other end of the knockout-arms straddle the knockout-rod 76 between the head 77 and the collar 78 thereon. Rotatably mounted between each pair of the knockoutlevers 74 is the cam-roll 79, which lies upon the periphcry of the knockout-cams 80, fixed to the shaft 65. The knockout-rods 76 are slidable within the fixed sleeves 81. Hcretofore it has been common to actuate the knockoutrod from a shaft directly beneath the rod; but this construction is objectionable in that the rods are not accessible or mounted so as to be readily removed. In my invention I have so designed and constructed the parts that each of the knockout-rods may be as sembled or taken down 'without disturbing any of the other. other rods, it being simply necessary to remove the pin 82, which passes down throu 11 the lugs 73 and holds the stud 75 against isplaccment, after which the levers can be disengaged both from the lug 73 and the knockoutrod, which can then be readily removed.

Fixed upon the top of the bed is a bolsterplate 83 of any preferred construction and u on the top of which are a plurality of dieb ocks 84, corresponding in number with the plun ers, and in each of these die-blocks is fitte such tools as are necessary to perform the successive operations. In Fig. 3 I have shown a drawing-die 85 as fixed therein and into which the punch 24 enters during the downward movement of the plungers 9, the knockout-rods 76 being in thesame axial line as the plungers 9.

The carr ing mechanism comprises the two aralle bars 86 and between which the punches and dies are operative; crank-plates 87, which are provided upon their periphery with the intermeshlng teeth 88; the crank blocks 89, which are slidable within slots 90 in the bars 86; coil-springs 91 at either end of said bars and connecting the same, the normal tension of which draws the said bars together, and spindles 92 and 93, which are rotatably mounted in brackets 94 and 95, fixed to the ends of the frame 1. A rotary movement is imparted to the spindles 92 and 93 and through the crank-plates 87 an in-a-ndout movement to the bars 86 by the earns 96, which are fixed upon the shaft 65, bell-cranks slide; finger tips s 97, mounted upon studs 98, fixed in the frame 1 and carrying a roll 99 thereon, which lies upon the ieriphery of the cams 96, one arm of the sai crank 97 engaging the end of a slide 100, that is movably secured by the vbolts 101 to a depending lug 102 upon the brackets 94 and 95, which slide abuts at its opposite end against an arm 103, fixed to the lower end of the spindle 92. The cam 96 is constructed with two plates, as shown in Fi 's. 10 and 12, and peri herally adjustable in re ation to each other y means of the bolts 104, movable in the slots 105, this adjustment permitting a variation of the time required to perform either the in or out movement of the bars 86.

The mechanism for imparting a lengthwise movement to the bars 86-that is, a motion parallel to the front of the machinecomprises the cam 106, which is fixed upon the end of the shaft 65; slide 107,having a slot 103 therein, within which is slidable a block 109, loosely mounted upon the shaft 65; rolls 110, which are mounted upon the slide 107 and lie in the path of the cam 106; link 111, fixed to said slide at one end and adjustably secured at its other end to an arm 112 upon the rock-sleeve 113, having the upwardlyprojecting arm 114 integral therewith; shaft 115, fixed within arms u on the bracket a slide 116, mounted in t e overhanging portion 117 of the bracket 95 and connected with the arm 114 by the link 118; rolls 119', fixed in the ends of the bars 86 and lying within the recess 120 in the top of the slide 118. The mechanism for adjustably securing the link 111 to the arm 112 comprises a late 121, removably secured to said arm 112 liy the bolts 122 and 123. The rotation of the earn 106 im arts a vertical movement to the slide 107 an throu h the link 111 a rocking movement to the s eeve 113 and an end- Wise movement to the slide 116 and bars 86 through the arm 114 and link 118. This endwise movement does not interfere with the in-and-out movement, as the rolls 119 move within the grooves 120 and the springs 91 always exerting a tension todraw the bars 86 to ether.

he carrier-finger mechanism comprises the saddles 124, having tongues 125 thereon, which lie in the groove 126 in the bars 86 and have a limited endwise adjustment upon said bars; slides 127, which are normally moved in one direction by a spring 128,which abuts at one end against a ii 129 upon said 130, secure to said slide; eccentric bloc 131,'which are adjustably secured to the slides 127 by the bolt 132. The finger-tips 130 are shaped so as to conform with the contour of the metal at each of its successive operations, and the eccentric IIO roll 131 is adjusted so that the lpressure of the ried from one punch to another without crushing it.

In operation the metal strip is first placed between the stops 64 u on the guide-bars 63 and then passes throng between the rolls -18 and is presented beneath the double-acting plungers. At this time the gates 26 and 27 are actuated through the cam 34, and the blank is pierced from the strip by the action of the piercing-die connected with the gate 26. The drawing-punch 47 is then actuated and the pierced blank is drawn into a shell or cup, after which the piercing and drawing punches are withdrawn, and the knockout rod lifts the drawn shell from the die. The bars 86 are now moved inwardly and the opposing finger-tips upon the first set of carrierfingers engage the shell and hold it frictionally therebetween. The endwise movement of the bars 86 now carries this shell parallel to the front of the machine a distance equal to the distance between the plungers 9,

.and the out movement of the bars 86 re leases the hold of the fingerti s upon the shell, and it rests upon the top 0 the bolsterplate and the bars 86 return to their original positions. At the next rotation of the shaft another blank is cut out and the above operations repeated, except that at the next inward movement of the bars 86 the finger-tips 'of the second set of fingers engage the firstdrawnjshell and carry it beneath the first of the single-acting plungers. The first-drawn shell is permitted to rest upon the top of the bolster-plate because the endwise feed of the bars 86 is only equal to the distance between the centers of the single-acting plungers, and as the distance between the center of the double-acting plungers and the first sin le-acting plunger is equal to twice that of t e singleacting plungers the shell must be lifted and carried twice the distance from the doubleacting plunger to the first single-acting plunger, after which the feed of the carrying mechanism is just sufficient to carr it from one single-acting 'lunger to the next one. After the shell has been operated upon by the last single-acting plunger it is permitted to drop from the machine and into a receptacle conveniently arranged to receive it.

There are many minor changes and alterations that can be made within my invention aside from those herein suggested, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly Within the spirit and scope of my invention.
